The process of preparing polyurethane elastomers can be roughly divided into three stages: prepolymerization reaction, chain extension reaction and post-treatment. Each stage has its own specific purpose and operational key points.

  1. Prepolymerization reaction: This is the first step and a critical step in the entire preparation process. At this stage, the low-free TDI trimer reacts with the polyol to form a prepolymer. In order to ensure that the reaction is sufficient and uniform, the reaction temperature and time must be strictly controlled. Usually, the temperature at this stage is controlled between 70-90°C and the reaction time is 1-2 hours.

  2. Channel extension reaction: On the basis of the prepolymer, a chain extender is added to further increase the molecular weight and cross-linking degree. This step is crucial to improve the mechanical properties of the elastomer. The chain extension reaction is usually carried out at higher temperatures, between about 100-120°C, and lasts about 30 minutes to 1 hour.

  3. Post-treatment: After completing the chain extension reaction, the product needs to undergo post-treatment steps such as cooling, curing and post-mature. These steps help eliminate internal stress and improve dimensional stability and final performance of the product.

Detailed explanation of process parameters

To better understand the specific operation details of each stage, the following table lists the key process parameters and their functions:

Stage parameters Recommended Value Function
Prepolymerization reaction Temperature 70-90°C Control the reaction rate to ensure sufficient reaction
Time 1-2 hours Ensure the reaction is complete and avoid by-product generation
